Air pollution is one of the greatest environmental health risks of our time. It is the second most common cause of non-communicable diseases like stroke, cancer, and heart disease, and it annually leads to around seven million premature deaths.

According to the World Health Organization (WHO), almost 90% of people worldwide breathe polluted air. Even though we can say that air pollution is impartial, affecting people regardless of gender, race, social class, or economic status, the burden of ill health caused by air pollution primarily affects middle and low-income cities and marginalized populations. The economic cost of air pollution and its impacts on health is known as non-market costs and includes the monetized welfare costs of mortality (premature deaths), and of the disutility of illness (pain and suffering).

Muye Ru, a 2019 Young Scientist Summer Program (YSSP) participant, is studying the main health impacts of air pollution and what this means for the economy and social development of a country. Her project will establish a methodology based on meta-analysis, to estimate the economic costs of selected morbidity outcomes of exposure to air pollution in a population, and test its application at various geographical scales (national, regional, and global).

“The idea behind my work is that bad air quality causes a burden for societies. We know that many people will die or be disabled because of it, but we don’t have a very good understanding of exactly what the social and economic cost of that is,” explains Ru.

It is easy to grasp that the burden of sick and disabled people will affect the economy of a country. For example, imagine a scenario where a family member is diagnosed with lung cancer. The illness will most probably influence the entire family in terms of loss of income when the person is unable to work due to his/her illness, or reduced funds available for savings and necessities like food and utilities due to the cost of treatment.

Ru’s project specifically focuses on the rate and duration of air pollution related-diseases in populations. According to her, this rate is extremely important once you start studying the high economic losses and social disturbances caused by illness and healthcare expenditures.

“It’s about how people are disabled, the effect of this burden on their lives, as well as how these changes in their lives are impacting the economy,” she says.

Ru hopes that her work will be useful to policymakers in creating and applying policies to combat air pollution that will lead to multiple benefits for the economy, the environment, and human health. She wants her research to make people more aware of how they are contributing to air pollution and how the cost of it affects everyone’s lives.
